This is actually life-changing for many people.
Paralysis of the lower body can, literally, be a drag on one’s sex life. However, makers of the IntimateRider claim that their device will allow people with certain disabilities to bring real action into the bedroom. The chair provides users with improved mobility during sex through the use of low-friction bearings and a spring-less design. No electricity or outside power source is required; use of the chair simply requires that the user be able to move their upper torso.
